  • hot melt adhesives used in the manufacture of a disposable absorbent article.
  • adhesives are used in construction (e.g. bonding the back sheet to the nonwoven and optionally the absorbent pad), elastic attachment (e.g. bonding the elastic material to the back sheet in for example the leg or waist area) and for the core stabilization (e.g. applying an adhesive to the absorbent core to increase the strength of the core).
  • Hot melt adhesives for elastic attachment applications formulated with polyolefin polymers tend to have higher creep, especially at body temperatures and under stress, than those formulated with styrene block copolymers (SBC). It would be desirable to use polyolefin polymers in hot melt adhesives for elastic attachment applications as they tend to have a lower odor.
